Hot foil stamping process

There are Five types of hot stamping presses according to the stamping methods and substrate's shapes.

Heat transfer Process

1.Roller-to-Flat Hot Stamping

Roller-to-flat hot stamping,is actually based on the principle of flat heat-transfer press,which is primarily used to decorate the planar objects and curved objects.Typically,a object that is completely required to be decorated,appliance panel,some facet of cosmetic packaging,top of the plastic box or wooden jewelry box,toys,PVC sheet,ski,and plastic posts are suitable to be decorated by a roller-to-flat hot stamping press .If a floating device is installed on the working station,roller-to-flat hot stamping press is also used to decorate the complex objects. H-150M and H-300M belong to this type.

2. Rotary Hot Stamping

Rotary hot stamping is based on the principle of rotary heat-transfer press. Most of Heat transfer machine can transfer both flat and round object. When trnasfer Flat object, The roller press down, The working table move from left to right; When transfer round object, The roller press down, The working table keep stillness and Object turn round.

(1)For Empty Platic Bottle

For the rigid bottle,is able to endure the pressure of roller.so,such bottle is directly decorated plus an axis position system;For the pliable bottle,is decorated after the bottle full of air to support the roller.

(2)Plastic Pliable Tube

Toothpaste,shampoo,bodycare,gel's container,or tubes are dcorated by this press if a supporting axis is installed.

Forme of hot stamping machine

Silicon rubber rubber is used in the processes of flat-to flat hot stamping and flat-to-roller technology,and silicon rubber roller in the rotary hot stamping and roller-to-flat process.They function as heat transferring and pressure offset. Silicon rubber plate and silicon rubber forme is more soft, suitable for stamping on plastics, Wooden, Glass, Metal surface.

1.Heat Transferring

In the processes of hot stamping and heat-transfer technology,the adhesive on the top layer of the foil or heat-transfer material is melt by the heat transfered over a silicon rubber plate/silicon rubber roller and the graphic is achieved on the objects.

2.Pressure Offset

In the processes of hot stamping and heat-transfer technology,silicon rubber plate or silicon rubber roller can provide the plastic objects with the pressure offset during the process.Therefore,they are usually used to decorate the more rigid objects rather than paper and films.

3.Color

There are a few colors for these silicon rubber plate and silicon rubber roller,eg.red,white,yellow,black,etc.,among which,red silicon rubber is the most popular in the hot stamping process.

4.Rigidity

Rigidity,is a key factor for the elastic substance,such as rubber.So is silicon rubber plate or silicon rubber roller.Rigidity,indicates the elastic substance's ability to resist to the physical force.More rigid,less distorting under the same physical force.Therefore,under the same physical force,a more rigid silicon rubber plate or silicon rubber roller can produce the more sharp and accurate texts or graphics.You can utilize a Shawn sclerometer to test the rigidity of silicon rubber plate or silicon rubber roller.

5.Thickness

Usually,silicon rubber plate consists of aluminum backing and silicon rubber layer,which are fixed together through a layer of metal-nonmetal adhesive.Thicker the aluminum backing,more even the rigidity of the silicon rubber plate/roller.The less thicker aluminum backing means flexibility,which means to readily setup the silicon rubber plate/roller's position for the operator.

Metal stamping forme.

In the field of paper package industry. Metal stamping forme used more widely. If you want get impression, Embossment, embossment and gilding, searing effects, You must use Metal stamping forme.Embossment Gilding Forme:
Including one pc Engraved copperplate and one pc Resin plate. Use this type Forme, you will get embossing and gilding effects;Embossment forme:
Including one pc Engraved copperplate and one pc resin plate. use this type forme, you will get embossing effects;Engraved Copperplate: Get impreesion on paper, leather, plastics surface;Etching copperplate and etching Zn-plate: Stamping words on Paper, plastics film surface.
